Abstract: A system, method, and apparatus for preventing one with dirty hands from entering or exiting an area without first using a hand washing system. Typical uses would be in hospitals, where patients are endangered by health care workers who may propagate microorganisms and thus illness from patient to patient. The subject technology seeks to stop one from passing by having a barrier block passage. Overrides for bypass system on an emergency basis or when hands are otherwise necessarily occupied, such as in carrying a tray or other objects. Sensors detect presence of obstructions in the movement of the barrier. Further, the barrier may be broken should an emergency arise. Current implementation presumes that one's hands are dirty, and thus entry or exit is initially denied. Once hand washing has occurred, then entry or exit is allowed.

These connections can provide for access to the control head through either tilting the head compartment assembly upwardly to expose the assembly cavity, in one structural embodiment, or downwardly to expose the cavity in another structural embodiment.

Abstract: In a turnstile with a housing, a drive shaft and barrier arms projecting therefrom at offset angles, after the right of entry of a passing user has been checked, a drive motor is started up contactlessly in order to rotate the turnstile from the blocking position of a barrier arm to a subsequent narrow-angle stop position. The approach of the user to the barrier arm in the stop position is recognized by an electro-optical sensor which is arranged behind the barrier arm in the direction of passage when in the blocking position in order to rotate the turnstile contactlessly into the next blocking position.

Therefore, the turnstile has the ability to detect and issue a signal for, a simulated walking-through attempt performed by a user who actuates turnstile revolving member (3) without actually walking-through said turnstile, and it proves particularly effective for checking the arrival and the presence of personnel at the working posts.

Abstract: A turnstile is made with a stationary turnstile support shaft extending from a solid support, and a bearing on the end of the shaft. The turnstile hub is supported on the end of the shaft with a bearing. The turnstile hub is locked against rotation in a fee-paid direction by a unidirectional pawl that engages a cutout on a ratchet plate attached to the hub. The unidirectional pawl is released by energizing a solenoid latching mechanism, rather than acting directly on the unidirectional pawl. Backcocking of the turnstile is prevented by a bidirectional pawl that engages notches on the ratchet plate. The bidirectional pawl is released by energizing a second solenoid latching mechanism, rather than acting directly on the bidirectional pawl.

The turnstile hub has an axis of rotation inclined at an angle of from about 38 to about 41 degrees from the vertical, most preferably at about 39 degrees from the vertical. A tripod of three turnstile arms of equal length extends from the hub with the arms lying along the edges of an equilateral pyramid having a pyramid apex that lies along the rotational axis of the hub. A second cabinet defining the other side of the passageway is spaced apart from the first cabinet.

Abstract: Two-way pedestrian access control system comprising a passageway laterally bounded by two pillars, said passageway being normally barred by a barrier locked in close position which can be opened upon validation by a system for recognizing individuals or passes, said barrier comprising a turnstile mounted to one of the pillars and consisting of three arms assembled in conformance with the edges of a regular trihedron and having an axis of rotation confounded with the ternary axis of symmetry of the said turnstile, said axis of rotation being so directed that the turnstile's rotation by 2/3.pi. about said axis always places an arm in horizontal position, barring the passageway, wherein said barrier further comprises a swinging gate, hinged about a vertical axis lying in the vertical plane containing the said rotational axis of the turnstile, said gate having a cutout enabling passage therethrough of the arms of the turnstile and being high enough to prevent from passing an individual of average size.

Abstract: A locking and releasing mechanism for a turnstile has a locking member which abuts a stop roller mounted on the hub of the turnstile at a spacing from its axis, to prevent rotation. A sleeve portion of the locking member is axially slidable in a cylinder and a plurality of balls retained in circumferentially disposed holes in the sleeve wall latch the member in its locking position by engaging in angled recesses in the cylinder wall. A latch release piston axially movable within the sleeve by an air motor has a peripheral groove and the locking member is unlatched by aligning the groove with the sleeve holes so that the balls disengage from the recesses and engage in the groove. The balls are urged towards the groove by springs and where present by axial loading of the locking member resulting from attempted rotation of the turnstile.

Abstract: It is a question of bringing resiliently and successively the arms of a turnstile to their position obstructing a passage to be controlled, and for this a rotary cam 1 in the shape of a star is used interlocked with the rotary assembly of the turnstile and a roller 2 resiliently applied against this cam.To avoid lifting-off between the roller and the cam, a second contact is used between a second roller 2 connected to the first roller or merging therewith and a second cam 10 connected to the first cam or merged therewith, the directions of application of the two roller-cam contacts being opposite.The invention applies to controlling access to urban rail networks.

Abstract: An access control system is disclosed wherein a passageway normally blocked by a gating structure such as a turnstile is opened to admit a person upon insertion of a coin into a coin slot, or upon insertion of an encoded card into a read head.

Abstract: A turnstile construction wherein arms normally block the path of movement of persons passing through the turnstile. The arms are engaged when authorized passage is available, and this results in movement of the arms either by the force of the person passing through or in a motor-assisted fashion. The head supporting the arms includes a control system including a drive gear tied to the arms for rotation during movement of the arms. Rotatable locking members are connected to the drive gear, and engaging arms are movable into and out of engagement with the locking members for purposes of controlling use of the turnstile. The engaging arms are normally controlled by the deposit of a proper fare whereby in the course of normal use, only persons paying a fare can pass through the turnstile. When locked, the system automatically protects against breakaway even when an extreme load is applied.

Abstract: A turnstile mechanism comprising a rotatable hub adapted to be driven by a person using a turnstile, the hub being connected to (or incorporating) a disc formed with a number of stop surfaces which are engageable by a stop member which is movable between a first position clear of the path of the stop surfaces and a second position lying in the path of the stop surfaces, the stop member being connected to control means which are operable to hold the stop member against a bias in either the first or second position, the control means being activated to change the position of the stop member from the first position to the second position when the hub has been rotated through a predetermined angle.
